` `Application aiedseptember a, 192e. serial no. 133,207.

This invention relates to a cooking receptacle, and method of making the saine,` and so far as the method is concerned is particularly applicable to making'the baking' pan'shown and described in myapplicationl.` Serial No.V

87,265, iiled February 10, 1926. p

The object ofthe invention, primarily, is vto provide a cheap, expeditious, and eliicent way of making a utensil designed to prevent burning of the contents, and to do away with the necessity of having to employ, in the bottom of the pan, greased paper or other materia-l, sometimes interposed betweenthe 1nner surface of a baking pan andits contents.

In the application referred to, there disclosed a baking panA comprising al body formed with innerfand outer walls,` suitably spaced apart (constituting the bottom. ends, and sides of the linished receptacle) and having a filling of asbestos, or other fire-proof material between the walls, the edges of the walls at t-heir'ends and sides, at the top of the pan, beingr securely united. y

It is import-ant that the filler he in close contact with the walls of the receptacle, and that every crevice and space therebetween `be filled in order to accomplish in the most-'eilieient manner, a baking operation in which the contents of -the pan is: unlormly cooked. To this end themethod about to be described contemplates forming the asbestos filling, in suitable moids, whereby it is shaped, substantially, in the exact shape of the space hetween the walls of the pan, and while the filler is moist. but sufiioient-ly set to handle. it is inserted in the bottom section oi the pan, which section .is meantime held inrrigid position, and the inner sect-ion of the pan forced down on the liller, and the edges of the pan crimped securely together.

The'introduction of the filler between the pan sections. and 'applying sutlicient force to make the filler conform exactly to the space between the pansections. is apt to cause the said sections to bulge or get out of shape. I, therefore, employ forms, whose surfaces are in intimate contact Iwith the outside and inside of the walls of the pan. The space between the outer and inner forms is exactly the shape of the main body-of the receptacle or pan, when in nished shape. Means are preferably provided for maintaining the inner and outer forms in properly spaced relation. Especially is it important to provide against the movement of the inner form in the operation of forcing it down upon the has been previously Y pan, as it is through the inner section oi" thepanthat the force com-i n'iunicated to the liller.,` which as intimated, shaped and substantially dried before it is Vintroduced between the inner and outer sections of the pan body.

The numeral l designates a baking nan formed in the maimof inner walls 2 and'oiiter walls 3. T he inner section is provided with a continuousiiange 3', and the lower section is provided with a short-er flange t, the two' flanges at their outer edges being crimped together as indicated at 5, thus securely fastening the two edges together. The pan thus formed comprises a hollow body with the walls suitably spaced apart, the space between the walls being for the purpose of receiving the filler of asbestos or other reproof material 6. This filler is shaped to conform to the` outer formation of the outer section of the pan, and is adapted to be received in said pan sec-tion with a close tit at all points.

The numeral 8 designates the inner shapere-taining form. This is shaped so as to tit snugly all parts of the inner section of the pan, and is provided with a iange 9, of a width sulicient to overlap that portion of die upper edge 0l the pun, inside of die peint of which (he inner und outer sections nre crimped logether. the flange l), serving lo force the edges of the pan sections, adjacenty the seams, into Close Contact with each other. so :is lo l'neilitnte the linul or crimping opernion, by which Jdie tvo pun sections nre secured logeher.

At the opposite end ell ihe outer form I preferably provide n clump ll, adapted to be rocked over on the `flange of the inner form to keep the two forms in properli)v spaced relition, und in close eonieel' with the inner und outer mills 0l the pan.
